CPVC Blind Flange
The CPVC Blind Flange is a solid disk flange used to seal the end of a CPVC piping system or isolate sections for maintenance, inspection, or future expansion. Made from premium-grade Chlorinated Polyvinyl Chloride (CPVC), this blind flange offers excellent resistance to high temperatures and corrosive chemicals, making it ideal for use in industrial, chemical, and water treatment applications. It is bolted to a companion flange and provides a secure, leak-proof termination point.

Key Feature of CPVC Blind Flange
- Pipe End Sealing: Effectively blocks off the end of a pipeline or unused flange connection.
- High Chemical Resistance: Withstands aggressive chemicals, acids, and alkalis.
- Thermal Stability: Handles high-temperature fluids up to 93°C (200°F).
- Durable and Rigid: Maintains structural integrity under pressure and environmental stress.
- Non-Metallic and Corrosion-Free: Perfect for harsh environments where metal flanges may degrade.
- Safe for Potable Water: Lead-free and non-toxic, suitable for drinking water systems.
- Easy Maintenance Access: Allows for convenient pipeline isolation during repairs or upgrades.
- Smooth Finish: Ensures a reliable gasket seal and minimal wear.
